Referencewill be hadto the accompany mg drawing, in which Figure 1 is a front elevation of the wheel.

.Figure' 2 is a vertl-cal cross sectional-elevation on line 2-'2.-

is'a circular cross of'Figure 1. Figure 3 section on an enlarged scale on line-33-of Figure 1. Figure tisga detailed feature of the rim on an enlarged scale. 1 indicates the ordinary front wheel rim, but this may have a shape adapted for any type of tire. The rim l'in this case forms the function ofthe ordinary iron tire and felloe-band of the" wooden wheel the wire wheel.

For purposes of removing the tire I provide the companion flange 2 asaseparate piece, which I by a series of bolts or screws 3. The draw- -1ng shows securing by screws entering small drop forged blocks 4:, provided with small flanges b by are secured, to the main rim 1 by rivets 6 passing throu h the wheel disk 7 which is the main mem er of the wheel?" The drawing indicates the screws as hav-,-

ing' roundedheads, but hexagon or square headed screws may be used if desired.

The main rim 1 is provided with a flange 8 which is turned over at 9 to form a shoulderfor the inner edge 10 of the companion flange or rim 2. Thus any shocks or severe loads that may be encountered by the flange 2, as inrunning alongside the car track wherein some projecting object might engage the flange g'instead' of therubher tire, will be taken up by the flange 10 resting against the flange 8, and not necessarily bei carried bytheserews 3, although they W111 such a load. The flanges 8' aid in carrying and 10 are not parallel to the plane of the wheel, but inclined as is also thecorresponding portion of the disk 7 This *0 permits the screws 3,-to pass freely through beautiful in appear-r the rubber tires applied 1 the bearings required for the and rear wheel I provide the adapter memmember 12. A

orthe ordinary rim of is secured to the main rim'l means of which the blocks 4 22 is that it makes a fillet in the bottom of I are easily. washed inclmation the 'holes in the flange 10 and yet when drawn tightly they exert an outward pressure to hold the flange 2 outward in its work as well as laterally to hold the tire in place.

11, indicates the ordinary pleasure car wheel hub madeas the same is made to suit ractice in use with wooden wheels and to a apt my disk 7 as a demountable disk fitting both the front her 12, which "passes ,over the normal inside hub and f "s secured thereto by rivets 13, p which pass through the flange 14 of the regular hub '11 and the flange 15 of my similar construction is provided for the rear wheel. 5 My'disk 7is made of a sheet of metal which is thinner at the margin and thicker around thehub portion and to give this disk strength and a slight degree of, elasticity I press in the swell or bulge 16 which merges into a series of radial corrugations 17.wh1ch terminate ina bearing on the surface 18 of v the member 12. p l 1 As shown, the flange 15 of the member 12 has corrugations 19 in which fit corrugations 20 of the disk 7. i

vide a corrugated clamping ring 21 which is corrugated in a peculiar manner, in that it 50 has very=deep corrugations at this outer margin 22, fitting the disk at this circle and a plain straight flange at its inner margin 23, the purposeof this feature of the flange ,85 the corrugations around the hub which facilitates the: washing and covers up the otherwise'square corner that would'occur if "this tapering feature of the corrugations of the fiange2l were not used.

The greatest strains on a wheeloccur im- 1 mediately around the hub and my corruga tions 17' furnish this extra stiffness required over a smooth plate and they thereby permit a much thinner disk to be used than if the 0 8- corrugations were not present. These corrugations add to the appearance andv theyand since they terminate but a shortdistance from the hub they allow thermain body .of the wheelte be per- Q wheel it is desirable that the wheel be rewashlng. I

The corrugations serve other purposes besides giving strength to the wheel, namely, this wheel is of the demountable type wherein the wheel and tire are demounted from the hub when occasion reqtlres a rapid change of tires well known in automobile practice. In this demounting of the entire fectly smooth for a fine appearance and easy 'moved as easily as may be and at the same time when it is secured in place it should be secured as rigidly as possible so as not to squeak or get loose in service. Where a plain disk is used and clamped on to the hub by a demountable fastening it has been found that even the slightest bit ot articulation, caused by small clearances in the fitting of the parts is seriously objectionable, so that the makers of disk wheels that are demonnted at the hub are compelled when using flat disks to make the fit so tight. that the wheels are demounted with inconvenience, but with my corrugated and inclined surfaces as indicated by Figure 3 the central bore and the fits around the bolt studs need not be close but may be free and when the bolts or studs are screwed up tightly the corrugations automatically make a tight lit against movements in any direction and yet when the screws or nuts are loosened the wheel will readily come oti.

In Fig. 3 there is a clearance indicated by 24: between the bottoms and summits ot the corrugations of the disk and of the llange 15 to which it is secured. This clearanc 2t causes contact to he made on the surt'aees 25 thus always insuring a snug position of the disk on the hub and making unnecessary any close fit of the disk on the studs or to the hub bore on which it is supported.

My disk is clamped to the hub through the medium of the stud bolts 26 provided with the nuts 27. The said bolts also assist in connecting the flange 15 to the ordinary hub flange 14 through which the stud 28 extends.

The nut 27 is provided with a lock washer 29 enclosed within the base of the nut.

The disk 7 is secured to the main rim 1, not only by the rivets and screws 3 when in place, but also by additional rivets 30 passing through the flange S and the margin of the disk only. The edge 31 ot the disk 7 is turned over to lit the inside of the tread of the rim and while I have not shown this portion 31, rivetedor otherwise secured to the rim, I will, with some thicknesses of disk plate, Weld or rivet through this portion 31 and the rim 1..

lVhat I claim is 1. A disk wheel composed of rim, disk and hub, said disk suitably connected to the rim and having a smooth, approximately e onical surface on the outer portion and a corrugations ot' the disk, means for clamping the disk at the corrugations to the hub.

2. A wheel compo-ed of a rim, disk and hub, said disk having a smooth body portion bulged in its middle region and provided with radial corrugations around the hub, the hub having a corrugated flange adapted to register with the corrugations ol' the disk and a series of studs or bolts adapted to secure the disk to the hub.

3. A -wheel composed of a disk, hub and rim, said disk suitably fastened to the rim and provided with a dished main body portion having at a distance from the rim an abrupt annular swell or bulge, for elasticity, merging into a series of radial corrugations 1" or stitlness around the hub, with means for clamping the disk to the hub.

4. In a disk wheel, the combination with the hub and a rim, of a disk body eXtend-' ing between the hub and rim, the wheel provided adjacent the hub zone with relatively short pocket-like depressions of substantial depth terminally merging into the general plane of the disk, and the outer zone presenting an unbroken surface.

53. In a disk wheel, the combination with the hub and rim, of a disk body extending between the hub and rim, the wheel provided adjacent the hub zone with annularly spaced depressions terminally abrupt at one end and at the other merging into the general plane of the disk, and the outer zone presenting an unbroken surface.

6. In a disk wheel, the combination with the hub and rim, of a disk extending between the hub and rim, the wheel provided adjacent the hub zone on one side only with annularly spaced depressions of substantial depth, and the outer zone presenting an unbroken surface.

7. In a disk wheel, the combination with the hub and rim, of a disk body extending between the hub and rim, the wheel provided adjacent the hub zone with annularly spaced depressions of substantial depth with their terminal portions abrupt at one end and at the other merging into the general plane of the disk, and the outer zone presenting an unbroken surface.

8. In. a wheel the combination with the central hub portion and the peripheral rim portion, of an intermediate forwardly concave disk portion, the circle of its greatest depth dividin; the disk into an inner and an outer zone, the inner zone provided with radially extending spaced pocket-like depressions and the outer zone having a substantially smooth surface.

9. In a wheel. the combination with the central hub portion and the peripheral rim portion, of an intermediate forwardly concave disk portion,' the circle of its greatest depth dividing the disk into an inner and an outer zone, the inner zone provided with radially extending spaced pocket-like depressions and the outer zone having a substantially smooth surface, and a radially corrugated or fluted hub member inter locked fwit-h the depressions of the disk and secured to the hub propen Si ned at Chicago, in the county of Cook f and tate of Illinois, this third day of September, 1919.
